JAJSEG5A January 2018 – October 2018 ADS112U04
As Table 15 shows, the device offers six different commands to control device operation. Four commands are stand-alone instructions (RESET, START/SYNC, POWERDOWN, and RDATA). The commands to read (RREG) and write (WREG) configuration register data from and to the device require additional information as part of the instruction. For clarity, Table 15 shows the command bits MSB first, but data are always transmitted byte-wise LSB first on the ADS112U04.
